Subject: [PATCH 0/2] irqchip/gic: Fix handling of Samsung's non-standard GIC
Date: Tue, 15 Sep 2020 14:39:42 +0100	[thread overview]
Message-ID: <20200915133944.1285456-1-maz@kernel.org> (raw)

Marek pointed out that the new IPI code broke the two ancient A9
platforms that use the dreaded Franken-GIC (not the official name), as
it appears it is even more broken than we though 9 years ago.

The fix isn't nice, although it allows for some further cleanup.

Marek, could you please give these another spin on your boards? For
convenience, I've stashed them as part of [1].

Thanks,

	M.
